Microbial transformations of natural antitumor agents: conversion of lapachol to dehydro-alpha-lapachone by Curvularia lunata.
نویسندگان
چکیده
Microbial transformation of lapachol, a naturally occurring naphthoquinone, was carried out by Curvularia lunata (NRRL 2178). The fungus brings about oxidative cyclization of the substrate to dehydro-alpha-lapachone, which was isolated and characterized by nuclear magnetic resonance and mass spectral analyses; its structure was verified by chemical synthesis. The metabolite is a naturally occurring chromene possessing antibacterial and antitumor activities.

Naphthoquinones are compounds present in several families of higher plants. Their molecular structures confer redox properties, and they are involved in multiple biological oxidative processes. In folk medicine, especially among Indian populations, plants containing naphthoquinones have been employed for the treatment of various diseases. The biological redox cycle of quinones can be initiated ...

متن کاملCloning and sequence analysis of a novel NADPH-cytochrome P450 reductase gene from filamentous fungus Curvularia lunata
Microbial transformation is an essential component for the commercial production of numerous valuable steroid drugs such as hydrocortisone, prednisolone. Steroid hydroxylation at C11 and C15 positions by filamentous fungi is routinely employed in the steroid industry due to both the necessity of regioand stereoselective oxyfunctionalization of unactivated C-H bonds of valuable steroid compounds...
